VENTILATOR AND PINNING FLAP F OR Q, 1 MATTRESSES Paul Spagnoli, San Francisco, Calif. Application June 1, 1948', Serial No. 30,487

3 Claims (01. 5-345) ventilators and pinning flaps for mattress.

It consists of the combinations, constructions and arrangement of parts, as hereinafter described and claimed.

An object of my invention is to prov1de a mattress having pinning flaps secured thereto by conventional ventilators, the latter placing the interior of the mattress in communication with the outside atmosphere. These flaps are adapted to have fastening strips attached thereto, which are used for retaining a youngster in its crib, or to have sheets and other bedding anchored thereto.

It is proposed in this invention to provide flaps having the entire marginal .portions thereof free and flexible, with the flap-anchors arranged at the central parts of the flaps. This construction allows strips to be fastened to the flaps with the pull on the strips always emanating radially away from the center of the flap-anchors.

Another object is to provide pinning flaps, which are arranged in such a manner on the mattress that the mattress may be inverted, and still allow fastening strips, or other bedding, to be secured to these flaps.

Other objects and advantages will appear as the specification continues; The novel features will be set forth in the claims hereunto appended.

For a better understanding of my invention, reference should be had to the accompanying drawing, forming .part of this application, in which:

Figure 1 is a perspective view of a mattress having my pinning flaps anchored to opposing sides thereof;

Figure 2 is a fragmentary side elevation of a portion of the mattress and a pinning flap; and

Figure 3 is an enlarged vertical sectional View taken along the line IIIIII of Figure 2.

While I have shown only the preferred form of my invention, it should be understood that various changes or modifications, ma .be made within the scope of the annexed claims without departing from the spirit thereof.

Referring to the drawing, I have illustrated a conventional mattress indicated generally at A. This mattress includes top and bottom surfaces I and 2, respectively, opposing sides 3 and opposing ends 4, all of usual construction. A plurality of pinning flaps B are anchored to'the opposing sides of the mattress at points spaced inwardly from the opposing ends thereof. The flap-anchors are designated generally at C.

The flaps B have been disclosed as consistz 7 ing of flexible discs of fabric, but I do not de sire to be limited'to this particular shape; It should be noted that the flap-anchors C are disposed at the central part 5 of the flaps, leaving the entire margina1 portions 6 of the flaps free for flexing away from the mattress, as suggested by the dot-dash lines in Figure 3.

Fastening strips D are often employed for re-' taining a youngster in its crib. The free marginal portions 6 of the flaps B are admirably adapted for having the strips secured thereto by safety pins I, or other suitable fastening means. The flaps can be flexed away from the sides 3 of the mattress to allow the pins 1 to be inserted or removed. It should be noted that the strips D can be attached to the flaps so as to extend radially from the center 8 of the anchor C. In this way, pull on the strips Dwill be directly away from the anchor C, which will aid in preventing the flaps B from being torn loose from the flapanchors.

In Figure 2, I disclose fastening strips DI that extend angularly relative to the mattress However, the pull on these strips are still away from the center 8 of the anchor C. When the mattress is inverted, a fastening strip D2 may beattached to the flap B so as to extend over the surface of the mattress that is uppermost at that time. The flaps B are disposed substantially intermediate the top and bottom surfaces I and 2, respectively. Of course, any part of the bedding, such as a sheet, can be attached to the pinning flaps.

The flap-anchors C are conventional in design. They include outer and inner flanges 9 and If], respectively, between which the flaps B and mattress sides 3 are clamped. Washers H are confined between the flanges I9 and the upset ends I2 of tubes 14 forming parts of the anchors C. These washers bear against the innermost surfaces l5 of the mattress sides. The anchors C have perforated discs [6 clamped within the double-thickness of the outer flanges 9 (see Figure 3). The perforations in these discs and the bores I ia of the tubes I4 place the interior Al the mattress in communication with the outside atmosphere.

It will be seen that the anchors C serve a dual purpose of providing the necessary ventilation for the interior of the mattress and at the same time retaining the flaps B in place.

I claim:

1. In a pinning flap construction of the character described: a normally flat piece of flexible fabric material; this material having a side face butted flatwise against a supporting member to provide a pinning flap; and means securing a cen tral part of the flap to the member; and leaving the entire marginal portion of the flap free for ready flexing away from the member, whereby a fastening strip may be pinned to any selected marginal portion of the flap, with the pull of said strip emanating radially away from the flapsecuring means. I

2. In a pinning flap construction of'the character described: a normally fiat disc-shaped piece of flexible fabric material; this material having a side face butted flatwise againstga supporting member to provide a pinning flap; and means disposed concentric with the peripheral edge of the flap, but spaced inwardly therefrom, and securing the flap to the member {on arcircular path extending around the center of the flap; the entire circumferential portion of the flap disposed between its periphery and the flap-securing means being free for'ready :fle-xing away r'om1the1mem her .to vfacilitate .pinninga lfastening strip thereto.v

3. In combination: a supporting member; a normally fiat piece cf flexible fabric material hav= ing a side face butted flatwise against the member to provide a pinning flap; means securing a cn= tral part of the flap to the member, and leaving the entire marginal portion of the flap free for ready flexing away from the member; and a fastening strip attached to a selected marginal portion of the :f.lap, with the strip vemanating radially away from the flap-securing means.
